You can now search for things such as persian* and/or *persian* to return all posts which have any keywords which contains *persian*
Searching for something like *gfy* will return too many results but searching for *ake* would not.
Try some searches on
http://www.***************.com and post here whether you find those results useful, and if you have problems post here too!
The next step will be implementing EXACT search terms.
Enjoy!
